Vehicle seat support structure

A vehicle seat support structure comprising

• a) a vehicle seat base,
• b) a seat cushion frame element,
• c) a crank, the crank being pivotally linked by a crank joint to the vehicle seat base,
• d) a front link, the front link being pivotally linked by a first front link joint to the seat cushion frame element and being pivotally linked by a second front link joint to the crank,
• e) a rear link, the rear link being pivotally linked by a first rear link joint to the seat cushion frame element and being pivotally linked by a second rear link joint to the vehicle seat base,
• f) a first actuator connected to the crank for pivoting the crank about the crank joint relative to the vehicle seat base and
• g) a second actuator connected to the rear link for pivoting the rear link about the second rear link joint relative to the vehicle seat base,
• h) bases of the first and second actuator being supported on the vehicle seat base,
• i) the first actuator comprising a first transmission with a first pinion gear meshing with a first toothed rack, the first toothed rack extending in a first longitudinal region,
• j) the second actuator comprising a second transmission with a second pinion gear meshing with a second toothed rack, the second toothed rack extending in a second longitudinal region and
• k) the first and second toothed racks are laterally offset from each other and the first and second longitudinal regions having an overlap in a longitudinal direction.
